Edinburgh's Kris Gilchrist insists his move from Scotland to Paris will soon start paying dividends.

Gilchrist, a world short course champion, took a big chunk out of his personal best but missed out on qualification for tonight's 50m breaststroke semi-finals at the World Swimming Championships in Rome.

But he's focussed on his priority event, the 200m breaststroke, later this week.

Gilchrist switched his training base to France after last year's Olympics to follow coach Fred Vergnoux, who also guided the career of former world silver medallist Kirsty Balfour.

"Fred's philosophy is different to other swimming coaches," he said.

"It has taken me a year before I started to see vast improvements. One thing he does is place land training equal to swimming work, rather than only a compliment to it.

"I was almost half a second inside my personal best and that is quite pleasing looking ahead to the 200m.

"Whenever you go into a major international meeting and you don't get a personal best time you will be disappointed.

"I'm not going to work on anything specific between now and the 200m, I feel in good shape."

British team-mate James Gibson also missed out on advancing with South Africa's Cameron Van der Burgh the quickest qualifier in a championship record 26.92 secs.
